2nd InterOp Workshop on Embedded Linux in Zynq (5.3.2020 in Brno, CZ)

The aim of the workshop is to provide professionals from industry and academia with knowledge on selected topics of software defined radio and its use in practice. The workshop introduces Embedded Linux (Petalinux) in Zilinq FPGA devices from Xilinx and focuses on embedded system problems starting with a higher operating system. Detailed information can be found in the invitation.

The workshop will be held on 5.3.2020 at the SIX Research Centre, Brno University of Technology.

Please find a pdf-version of the program here: Invitation WS 2020_03_05.pdf

Updated functionality of the SDR emulator

New documents and designs are available for download. New features include a system update application for Xilinx Zynq-7000 devices. The application includes a simple embedded HTTP server for a remote file transfer. A client is allowed to upload the boot image file with the system update from either command line application or using the web page developed for this purpose.

InterOP investigates LoRaWAN

Due to the high demand from industry, InterOP decided to widen its scope to include LoRaWAN system. The InterOP team will setup an open source based loraserver.io implementation utilizing an RaspberryPi 3 + IMST iC880A gateway. This setup will be used to investigate LoRaWAN systems with respect to the increasing in-band interference.

Although the InterOP team is already aware of connection- and range-problems in the field, we encourage companies to share their specific problems with us.

Cooperation of InterOp with University of Sheffield (UK)

The InterOp team at BUT joins a global test network for planet-scale performance analysis. The University of Sheffield has deployed a LoRa base-station at BUT, providing a GPS receiver and a range of sensor interfaces for metering or monitoring of electrical power reliability and availability. Further LoRa base-stations are available in the following locations:
-    Sheffield, United Kingdom
-    Loughborough, United Kingdom
-    Prague, Czech Republic
-    Brno, Czech Republic
-    Tampere, Finland

Low-cost interference emulator

Due to the demand of complexity reduction in interference emulation, a digitally stepped noise source has been developed. The noise bursts are modulated according to the statisticsgenerated by the interference measurement campaign in June. Please have a look on our goals page for further details.

Interference measurement campaign

In the end of June, we managed to capture ISM band traffic (2.4GHz & 5GHz) in WiFi Channels during the lecture “Computer Supported Japanese”. Subsequently, this data will be analyzed to characterize traffic load, amplitude distributions and many more. For our latest results, refer to the following link.
